METHOD FOR THE PREPARATION OF A FINE-GRAINED MIXTURE HAVING HYDROPHOBIC PROPERTIES |
摘要 |
Preparation of a fine-grained mixture having hydrophobic properties and a grain size substantially less than 0.2 mm and preferable less than 0.1 mm for asphalt-treatment and de-icing, having a hydrophobic component with a hydrophilic component of at least 50% by weight of the mixture and having 55-99.5 % by weight of a residual salt which results from the production of glycerol and 45-0.05% by weight of an additive consisting of salts, oxides, hydroxides, and combinations thereof, in the moist condition and at least partially ground with the residual salt, and containing alkali-earth metal or other non-alkali metals as cations.
